The document discusses the role of carbohydrates in dental caries (tooth decay). It states that fermentable carbohydrates like glucose, fructose, and sucrose are easily fermented by bacteria like Streptococcus mutans in dental plaque, producing acids that demineralize tooth enamel and lead to cavities. Frequent sugar intake and sticky sugars that remain on teeth increase caries risk. Starches carry less risk as they are slowly broken down. Replacing sucrose with non-fermentable sugars can reduce caries. The acidogenic theory proposes that the localized pH drop facilitated by plaque enables demineralization.

Histopathology & microbiology of dental caries
The document summarizes the histopathology of dental caries. It describes how dental caries is a microbial disease that causes demineralization of tooth enamel and dentin. It discusses the role of bacteria like Streptococcus mutans in producing acid that dissolves tooth structure. The summary describes the microscopic appearance of carious lesions in enamel and dentin, including the formation of zones of demineralization and bacterial invasion of dentin tubules over time. Advanced caries can ultimately lead to tooth cavitation and pulp involvement if left untreated.
DENTAL CARIES
Dental caries is caused by demineralization of tooth structure due to acid produced by oral bacteria. It is characterized by loss of both inorganic and organic components of the tooth. Dental caries has been defined and classified in various ways based on factors such as the anatomical site, severity, tissue involvement, number of surfaces affected, and chronology. The key etiological factors include the presence of cariogenic bacteria in dental plaque, a susceptible tooth substrate, and a cariogenic diet. Secondary factors like time, the dynamic process of demineralization and remineralization, and saliva also influence the development of dental caries.
the cause of teeth decay
Tooth decay is caused by plaque bacteria in the mouth that feed on sugars and starches, producing acids that destroy tooth enamel. Left untreated, it can lead to cavities, abscesses, and other dental problems. Risk factors include frequent consumption of foods high in sugar like candy, chocolate, soft drinks, and carbohydrates without proper brushing and flossing. Maintaining good oral hygiene through regular brushing and flossing, limiting sugary foods and drinks, avoiding tobacco use, and a balanced diet can help prevent tooth decay.
DENTAL PLAQUE & CARIES
Dental plaque is a filmy deposit on teeth consisting of mucus, bacteria, food and other particles. It can lead to tooth decay, a process where enamel and dentin are demineralized and destroyed, potentially causing cavities. Factors that increase decay risk include foods high in sugar, poor oral hygiene, smoking, dry mouth and Sjogren's Syndrome. Decay happens when acids from plaque dissolve enamel. Dentists can detect decay through examining teeth for soft areas, probing with instruments, and taking dental x-rays to view the extent of cavities.
Dental Caries
Dental caries is caused by an interaction between fermentable carbohydrates, bacteria in dental plaque, and susceptible tooth surfaces over time. Streptococcus mutans and Lactobacillus species in plaque produce acid as they metabolize carbohydrates, lowering the pH and demineralizing enamel. Factors like restoration of teeth, diet, saliva, age, and fluoride exposure influence caries risk. Caries was historically attributed to worms or humors but is now understood as a chemicoparasitic process initiated by acid from plaque bacteria.
Dental Caries ; A Presentation by- MunabbiR
Dental caries, or tooth decay, is a microbial disease caused by bacteria in the mouth that leads to demineralization of tooth enamel and dentin. Key factors for development of caries include cariogenic bacteria, bacterial plaque, fermentable carbohydrates, and susceptible tooth surfaces. Symptoms may include tooth sensitivity, pain, and visible cavities. Diagnosis involves visual examination and sometimes x-rays. Treatment depends on the severity but may include fillings, root canals, extractions, or replacements like bridges or implants. Maintaining good oral hygiene through regular brushing and cleanings can help prevent caries.

Dental caries
Dental caries is caused by the interaction of four main factors: the tooth, dental plaque, diet, and time. Dental plaque is a soft biofilm containing bacteria like Streptococcus mutans that produce acid from sugars in the diet, causing demineralization of tooth enamel and leading to cavities. Diet plays a key role, as frequent consumption of fermentable carbohydrates like sucrose promotes acid production. Other factors like saliva, fluoride, socioeconomic status, and education can also influence risk. Dental caries is diagnosed visually, tactilely, and radiographically and can be classified based on location, extent, and rate of progression. Prevention focuses on reducing sugar intake, maintaining oral hygiene to

Dental caries
Dental caries is caused by bacteria in the mouth that metabolize carbohydrates, producing acids that demineralize tooth enamel and dentin. It progresses through stages from early subsurface lesions to cavity formation and bacterial invasion. Risk factors include diet, oral hygiene, tooth composition, and saliva. Treatment involves preventing demineralization through fluoride, controlling plaque and bacteria, and restoring teeth through fillings or other methods.
Dental caries , its etiology
Dental caries is caused by an imbalance between demineralization and remineralization of tooth enamel and dentin. It is a bacterial infection resulting from acids produced during bacterial metabolism of dietary carbohydrates. Key factors in the development of caries include the oral bacteria Streptococcus mutans, frequent consumption of fermentable carbohydrates, and conditions like low saliva flow that reduce the buffering capacity of saliva. The caries process involves a dynamic interplay over time between demineralization of enamel during periods of acid production, and remineralization when pH rises. If demineralization exceeds remineralization, it can lead to cavitation and destruction of tooth structure.
Dental caries 1
Dental caries, also known as cavities, are caused by bacteria in the mouth that feed on sugars and produce acid, which demineralizes tooth enamel over time. The main bacteria involved are Streptococcus mutans and Streptococcus sobrinus. These bacteria live in dental plaque on the teeth. Factors like frequent sugar consumption, poor oral hygiene, and low saliva flow can promote the growth of these cariogenic bacteria and lead to tooth decay. Other contributors include tooth anatomy, acid erosion, and lack of fluoride exposure.
Dental caries
Dental caries is caused by an interaction between oral bacteria, fermentable carbohydrates, and tooth surfaces over time. Miller's chemico-parasitic theory is the most widely accepted explanation of the etiology. It states that acids produced by oral bacteria from carbohydrates lead to enamel demineralization and destruction. Clinical presentation varies and includes pit and fissure caries, smooth surface caries, and root caries. Histologically, caries progresses through zones of demineralization and remineralization in both enamel and dentin. Prevention focuses on modifying the oral environment, bacteria, and substrate to reduce acid production and demineralization.
Dental Caries
The document defines dental caries as a disease caused by bacteria in the mouth that ferment dietary carbohydrates, producing acid that demineralizes tooth enamel and destroys tooth structure. The major factors contributing to dental caries are certain bacteria like Streptococcus mutans; dental plaque that allows bacteria to adhere to teeth; saliva, which can increase the cariogenic effect while also helping to clean teeth; and consumption of fermentable carbohydrates like sugars, which feed the bacteria. The microbiology section notes that the main bacteria involved are streptococci and lactobacilli, while other bacteria like actinomyces may also play a role.
Dental caries
Dental caries is the most common microbial disease affecting the tooth. Even through extensive studies over the years, the pathogenesis remains questionable. Hence a fundamental understanding of caries and its theories is essential as data from the past serves as the most vital evidence in the unavoidable quest to figure out the pathogenesis.

39.erosion
Erosion is the chemical process of tooth substance loss without bacterial involvement. It occurs when tooth surfaces are exposed to acids from intrinsic sources like gastric reflux or vomiting, or extrinsic sources like acidic foods and beverages. Clinical features include smooth lesions on the front teeth surfaces that cause hypersensitivity. Radiographs may show radiolucent defects in the crown. Management involves diet control, fluoride use, changing brushing habits, and restorations or systemic treatment depending on the cause of erosion.
Biochemistry of dental caries
Dental caries, also known as tooth decay, is one of the most common health problems worldwide. It is caused by bacteria in the mouth that produce acids that dissolve tooth enamel. There are five stages of tooth decay. Cavities start small but can grow larger and deeper if not treated, potentially leading to tooth pain, infection, and loss. Regular dental visits and proper brushing and flossing can help prevent cavities. Treatment options depend on the stage of decay and include options like fillings, root canals, or tooth extractions.

Dental caries and periodontal diseases.ppt
1. Dental plaque is a biofilm that develops on teeth and comprises living and dead bacteria and their products embedded in an organic matrix. The microbial composition of plaque varies between individuals and locations in the mouth.
2. Gingivitis is a reversible form of periodontal disease caused by dental plaque. It involves inflammation of the gingiva without loss of attachment to the tooth. The gingiva become red, swollen and bleed easily but are not painful. Early plaque is dominated by streptococci while established lesions contain increased levels of anaerobic bacteria like Porphyromonas and Prevotella.
3. Dental caries is caused by acid-producing plaque bacteria metabolizing ferment
Denatal caries - Tooth Decay
Dental caries is caused by acid-producing bacteria in dental plaque that metabolize sugars from the diet. As the bacteria lower the pH, minerals are dissolved from tooth enamel and dentin, leading to cavitation. The primary bacteria involved are mutans streptococci. Risk factors include frequency of sugar consumption. Early lesions appear as white spots on smooth surfaces or pits and fissures. Untreated, caries progresses through enamel and into dentin, forming zones of demineralization and bacterial invasion.

The document summarizes various aspects of dental health, including that plaque consists of microorganisms and extracellular matrix, dental calculus is mineralized plaque that attaches to tooth surfaces, and dental caries are demineralization of enamel by bacterial waste products. The main factors influencing caries and calculus are oral hygiene and diet, with complex carbohydrates and refined foods associated with greater risks due to longer oral clearance times. Periodontal disease is influenced by plaque, hygiene, and diet, as bacteria from plaque and the mouth trigger an immune response leading to inflammation and potential tooth/bone loss.

Factors considered in diagnosis and treatment decisions are also summarized, including lesion activity, size, and depth. The goal of diagnosis is early detection to allow for preventive and minimally invasive treatment when possible.
Dental Cavity (Caries)
The document discusses dental cavities, including what they are, how they form, risk factors, signs and symptoms, diagnosis, and treatment options. Cavities are holes in teeth caused by tooth decay from bacteria in the mouth interacting with sugars. They start small in the enamel and get deeper over time. Risk factors include diet, saliva flow, and genetics. Cavities are often diagnosed through dental exams and X-rays. Treatment focuses on prevention through diet and hygiene, remineralization of small cavities, and restoration of larger cavities with fillings or other procedures.

The document provides an introduction to dental caries (tooth decay) as a disease. It defines dental caries according to various authors and organizations. Caries results from an imbalance between tooth mineral and biofilm fluid that causes demineralization of enamel and dentin. Key factors that contribute to this imbalance are the host tooth surface, carbohydrates as a substrate for oral bacteria, the oral biofilm, and time. However, not all individuals with teeth and a biofilm who consume carbohydrates will develop caries, as several risk and protective factors can modify the caries process, such as saliva composition and flow, oral hygiene, fluoride exposure, and diet.

The document discusses the role of carbohydrates in dental caries (tooth decay). It states that fermentable carbohydrates like glucose, fructose, and sucrose are easily fermented by bacteria like Streptococcus mutans in dental plaque, producing acids that demineralize tooth enamel and lead to cavities. Frequent sugar intake and sticky carbohydrates increase caries risk as they prolong acid exposure. Starches carry less risk as they are slowly broken down. Replacing sucrose with non-fermentable sugars can reduce caries. Local acid drops below the critical pH of 5.5 cause subsurface demineralization and eventual cavities.

Frequent sugar intake and sticky sugars that remain on teeth increase caries risk. Starches carry less risk as they are slowly broken down. Replacing sucrose with non-fermentable sugars can reduce caries. The acidogenic theory proposes that the localized pH drop facilitated by plaque allows demineralization.

Chap4 lipid nutrition in health and disease
Lipids are a group of organic compounds that are soluble in organic solvents but not in water. They serve several important functions in the body including as an energy source, insulating and protecting organs, carrying fat-soluble vitamins, and as structural components of cell membranes. The basic units of lipids are fatty acids which can be saturated, monounsaturated, or polyunsaturated. Phospholipids are a class of lipids that make up cell membranes and play roles in processes like blood clotting. Cholesterol is a waxy lipid that helps form cells and produces hormones and vitamins, but too much can increase heart disease risk.
